Half-Day Leave
Also known as: partial day leave, AM/PM leave
Half-day leave is time off booked for part of a working day — a morning (AM) or afternoon (PM) — that deducts half a day from the employee's leave balance.
Half-day leave lets an employee take part of a day off instead of a full day, usually split into a morning (AM) and afternoon (PM) portion around the middle of the working day. It deducts 0.5 of a day — or the equivalent hours — from the leave balance rather than a whole day.
Supporting half-days makes a leave tracker far more useful for the real reasons people need a few hours off: a dentist or doctor's appointment, a school run, a delivery, a viewing, or an afternoon to catch a flight. It also avoids the waste of booking a full day when only part of one is needed.
AM vs. PM half-days
A half-day is normally booked as either the morning or the afternoon, split at the midpoint of that person's working hours. Recording which half matters for coverage — a manager can see at a glance that someone is out in the morning but back after lunch — and for calculating overlaps against blackout periods or minimum-staffing rules.
Because offices work different hours, the AM/PM split follows each office's configured working day rather than a fixed clock time, so a half-day is genuinely half of that person's day.
How the balance deducts a half day
When someone books a half-day, the tracker subtracts 0.5 days (or the matching number of hours) from their remaining balance instead of a full day. Over a year those halves add up precisely — two half-days equal one full day off — so entitlement is never quietly over- or under-counted.
The maths has to stay right when half-days combine with accrual, carry-over, and pro-rata entitlement for part-timers, which is exactly where manual spreadsheets tend to drift out of sync.
How Absenca handles half-days
In Absenca, employees pick a half-day and choose AM or PM when they request leave. The request flows through the normal approval process, the calendar and wallchart show the person as out for just that half, and their balance drops by exactly half a day. Half-days work for annual leave, sick leave, and TOIL alike.
Example
An employee with 12.5 days remaining books a Friday afternoon (PM) off for an appointment. Absenca deducts 0.5 days, leaving 12 days, and shows them as available until lunch on the team calendar.

Frequently asked questions
- How much leave does a half-day use?
- Half a day — 0.5 of a day, or the equivalent in hours based on the employee's working pattern. Two half-days deduct the same as one full day of leave.
- Can you take a half-day as sick leave or TOIL?
- Yes. In Absenca a half-day can be booked against annual leave, sick leave, or a TOIL balance — anywhere a partial-day absence makes sense — not just paid holiday.
- How is a half-day split between morning and afternoon?
- A half-day is booked as either AM or PM, split at the midpoint of that employee's working hours for their office. That keeps the split fair across offices that work different hours.
